There are reports of a “pavement buckle” located on the northbound Highway 99 in Richmond, ahead of the Oak Street Bridge.

News 1130 says a listener called in with details about what he saw while in a vehicle on the roadway: “It starts at about eight to 10 inches low on the grass side and comes up to grade, but it’s about five feet wide by about three feet long.”

UPDATE: BC’s Ministry of Transportation and Infrastructure said Tuesday in a release that the incident was a “culvert collapse.” Traffic has been reduced to a single lane and “engineers are on site conducting an assessment.”

The pavement buckle is a result of the culvert collapse, however at this time a cause for the collapse is not yet known.
